Rust Engineer | Defence Start Up

We’re working with an early-stage technology company building foundational software for complex, real-world systems. This is a hands-on engineering role with high ownership — you’ll design, build and deploy core components that power mission-critical applications across a range of operational environments. What you’ll do Build and maintain low-latency, reliable software for backend and embedded systems. Implement and optimise services in a systems language (Rust, C++, Go or similar). Integrate with sensors, devices or external data sources and support field deployments. Troubleshoot and iterate in production-like environments; write robust tests and documentation. Work closely with cross-functional teams to turn user needs into technical solutions. Who we’re looking for Strong programming experience in a systems or backend language (Rust, C++, Go, Java, Python). Comfortable with systems concepts: concurrency, networking, performance tuning, and resource constraints. Pragmatic problem-solver who can be hands-on from prototyping through to production. Good communicator; able to work with technical teams and non-technical stakeholders. Willingness to travel occasionally for on-site work and deployments where required. Nice to have Experience with real-time systems, robotics, or embedded integrations. Familiarity with containerisation, CI/CD, and cloud or on-prem deployment workflows. Background in building reliable software for mission-critical or high-availability contexts. Why apply Join early and have a direct impact — influence architecture, practices and product direction. Work in an engineering-first culture with autonomy and clear ownership. Competitive pay, equity participation, and a focus on professional growth.
